Application filed August 9, 1915. 'Serial No. 44,534.

To all whom t may concern.'

Be it known that I, CHARLES HUn'roREN, a citizen of the United States, resldlng vat Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Sofa-Beds, &c., of which the following is a specification.

This invention relates particularly to` sofa-beds of the type employing4 an innerl folded bed; and the primary object is to provide a structure of improved 'construction and operation, in which the length of the bed extends at right-angles to the back of the sofa-frame when the structure is in tion'al view of the structure in open condition; Fig. 2, an enlarged broken elevational view, being a fragmentary view of the seatframe and back frame and thefolding bed surmounting the seat frame in its overturned position; Fig. 3, a view4 similar to Fig. l, but showing the structure in the half open position; Fig. 4, a View similar to Fig. 3, but showing the structure in closed condition; Fig. 5, a broken plan section taken as indicated at line 5 of Fig. 1; Fig. 6, a View showing the seat-frame and sofaback frame in the relation which they occupy when the structure is in sofa form, and Fig. 7, an enlarged broken section taken as v indicated at line 7 of Fig. 6.

In the preferred embodiment, the invention comprises a main frame A; a forwardlyfoverturnable seat B; a back .C adapted to fold upon the seat and to be carried thereby to a position in front of the main frame when the 'structure is converted to bed form; and a folding-bed D which is housed partially the rear of the sofa-back when the structure is in sofa form.

The frame A, in the illustration given, comprises ornamental standards 1, whose lowerportions are connected by an inner rectangular frame 2. In the illustration given, the frame is provided with a closed back 3 and an ornamental top rail 4.

The inner open box, or frame, 2, is shown connected with the lower portions of the beneath the seat and partially in standards 1 by bolts 5. The front corners of the inner frame 2 are equipped with mountmgs, or standards, 6 having arms 6a from which ,are suspended links 7 which are connected with the base-portions of standards, or hangers, 8, applied to the lower front corners of the seat-frame.

'The seat B comprises a frame 9 and a cushion 10.

Referring to the structure in sofa form (Fig. 6), the rearportion of the seat-frame 9 has rigidly secured thereto plates, or standards, 1l, whose upper ends are connected, by `pivots or studs 12, with the lower portion of the frame of the cushion-back C. The upper portion of each plate or standard 1,1 is provided with a dog, or locking-device, 13, which is mounted on a pivot 14 and which is provided with locking notches 15 and 16, one or the 'other of which is adapted to engage a locking stud 17, with which the ad]acent portion of the frame of the back G -is provided, the locking notch 16 corresponding) with the, upright position ofthe cushion ack, as shown in Fig. 6, and the locking-notch 15 corresponding with that position of the back C when it is parallel with the seat B, as illustrated in Fig. 2.

As shown in Figs. 6 and 7, each dog, or doulble-lock pawl, 13, has connected therewith an actuating link 18 havingfguide-connections 19 with the seat frame, or with the corresponding plate 11 of the seat-frame.

'At the lower end of the link 18 is a laterally-turned member, or lug, 18a, which, when the seat is in they normal position shown in Fig. 6, .engages the upper edge of the endmember of the box 2, thereby lifting the link 18 and causlng it to move the pawl so that the notch 16 will engage the stud 17.

The plate 11 is provided with a segmental slot 11-l through which the stud 17 projects, and in which it moves when the back C is moved with relation to the seat. The frame of the seat B is provided at its lower edges with bores, or sockets, in which are confined *coiled springs 20, which serve to depress or hold down the links 18, and thereby release the studs 17 from engagement with the notches 16 when the-seat is lifted slightly in the initial portion of the operation of turning the back C forwardly upon the seat preparatory to swinging the seat forwardly to an inverted position in front of the main frame.

From the foregoing, it will be understood that the back C is locked in angular relation to the seat when the structure is in sofaform, andis locked in parallel relation to the seat when the structure is being converted to bed form.

The folding-bed D comprises a rear bedsection 21; a spacing section 22 pivotally connected with the section 21 and also pivotally mounted on the hangers, or standards, 8, carried by the seat frame; a main intermediate section 23 pivotally connected withl the spacing section 22, and a front, or footsection, 24, pivotally connected with the main intermediate section 23.

The rear b ed-section 21 is mounted on elbow-levers 25, which areconnected at one end, by pivots 26, to the frame-attached member Gand connected at the other end, by pivots 27, to the'ar'ms of the bed-section 21. i The intermediate section 22 comprises short bars which are connected by a truss 28, said short bars being connected with kthe hangers 8 by pivots 29. The levers 25 are connected With the hangers 8 by links 30. The portion of the main intermediate bedsection 23 which is adjacent to the footsection 24, that is the outer portion of the bed-section 23 when the structure is in bed form, is connected by links 31 to clips 32, with which the seat-frame is equipped at its free longitudinal edge.

rI`he bed-section 24 comprises a U-shaped Iframe-member, the extremities of whose arms are equipped with rigidly secured plates 33, which are connected, by pivots 34, to adjacent ends of the members comprising the main intermediate section 23. A truss 35 connects the corresponding joints of the folding-bed in line with the pivots 34, this being the usual -U-shaped truss. The plates 33 have up-curved free extremities, or arms, 33a, which are connected, by links 36, to the seat-frame B.

r1`he outer, or foot-section, 24, of the bed is provided with folding legs 37, which are connected, by links. 38, to the links 36. The construction is such that in the operation of swinging the seat to an inverted position, the links 36 will serve, through the medium of the arms 33, to extend the foot-section, and, through the medium of the links, 38, to unfold the legs. l

The rear corner portions of the rear bedsection 21 are connected, by springs, 39, to standards 40 secured to the rear corners of the inner frame 2. These springs serve as counter-balancing springs and aid in ythe operations of folding and unfolding the v structure.

.the bed which. normally. occupies an upstanding position, in the back of the sofa.

In the operation of swinging the seat to the inverted position, the bed-frame is unfolded and the legs 37 are also unfolded. When the structure is in bed-form, the frame of the back C rests upon the floor, while the seat rests upon lthe back and supports the intermediate portion of the bed.

In the reverse operation, the foot-section 24 is turned to a position at right-angles to the main intermediate bed-section 23, and the head-section 2l is lowered into the inner frame 2, the spacing section 22 finally assuming substantially a vertical position, while the section 23 assumes a position substantially parallel with the section 21. [he construction is such as to provide a space '4] between the sections 21 and 23 for the folded mattress and bed clothing, and a space 42 in the rear of the back for that portion of the mattress and bedding which is secured to the foot-section 24 of the folding-bed.

It will be noted that the structure obviates the necessityof storing three folds of a mattress and bedding beneath the seat,'so that the sofa-seat can be mounted low in the main frame.

The foregoing detailed description has' been given for clearness of understanding only, and no unnecessary limitation should be understood therefrom, but the appended claims -should be construed as broadly as permissible, in view of the prior art.
